SPC500A1 512KB SOUND CONTROLLER GENERAL DESCRIPTION www.datasheet4u.com The SPC500A1 is a CPU based two-channel speech/melody synthesizer including CMOS 8-bit microprocessor with 69 instructions, 512K-byte ROM for speech and melody data (Speech is compressed by a 4-bit ADPCM with approx. 120 sec speech duration @ 7KHz sampling rate) and 128-byte working SRAM. It includes two Timer/Counters, 23 Software Selectable I/Os, two 8-bit current outputs D/A (or one PWM audio output) and serial interface I/O port. It provides Multi-Duty-Cycle output for remote control purposes. For audio processing, melody and speech can be mixed into one output. It operates over a wide voltage range of 2.4V - 5.5V and includes Low Voltage Reset function.
